A cache card is a board you install inside your computer, specifically designed to temporarily store frequently used information that the computer would otherwise have to get from the disk. A cache card can dramatically increase the speed of many tasks because getting information from a cache card is much, much faster than getting the information from a disk.

Most computers built today either have a cache card built into them at the factory, or come with a slot inside the computer so you can add one at a later date. The beauty of a cache card is its price-often costing less than $200, this little jewel gives you "more bang for the buck."
